Furthermore, two position sensors are arranged in the moving range of the swing arm of the push arm gear.

Further, the footboard is located all to be provided with on the both sides edge of direction subassembly and connects the extension arm, two connect the extension arm and form with the cooperation of footboard side and dodge the district, linear bearing with be connected extension arm fixed connection.

Furthermore, a step lamp is arranged on the side edge of the body support corresponding to the front surface of the pedal.

Furthermore, a brush is arranged on the body support corresponding to the bottom surface of the pedal.

Furthermore, a buzzer is arranged in the body support.

Further, the body support is provided with a mounting support.

The utility model has the advantages that:

the linear bearing and the bearing guide pillar are matched to realize guiding movement, so that the device has the effects of small running resistance, energy conservation and reliability, and the thrust motor does not do useless work;

the flexible power portion is fixed in the body support, and between body support inside and the footboard promptly, consequently have sufficient installation accommodation space, lie in under the equal thickness's of current structure of marking time the condition, the preparation of arm gear thickness that pushes away of the flexible power portion of this application can greatly increased, consequently effective increase strength to adopt one to push away the arm gear and can realize promoting, reinforcing mechanical properties reaches durable purpose of using.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 and 2, an embodiment of the electric retractable step of the present invention includes a body support 1, a pedal 2 is disposed in the body support, guide assemblies 3 are disposed on both sides of the pedal, the guide assemblies are disposed toward the extending direction of the pedal, a retractable power portion 4 is further fixedly disposed in the body support, the retractable power portion pushes the pedal to retract, and the guide assemblies play a role of sliding guide when the pedal retracts;

the guide assembly comprises a linear bearing 5 and a bearing guide post 6, the bearing guide post is fixedly arranged in the body bracket, the linear bearing is fixed with the side edge of the pedal, the bearing guide post is fixed during telescopic movement, and the linear bearing axially moves along the surface of the bearing guide post to achieve the effect that only the pedal extends out; the linear bearing is matched with the bearing guide pillar, so that the linear bearing has the effects of small running resistance, energy conservation and reliability, and the thrust motor can not do useless work; and all be provided with on the both sides edge that the footboard is located guide assembly and connect extension arm 11, two connection extension arms form with the cooperation of footboard side and dodge the district, dodge the flexible power portion of district installation, linear bearing with be connected extension arm fixed connection, connect the extension arm and can make the footboard stretch out as far as, reach the effect of high utilization ratio. The telescopic power part is arranged in the avoiding area, so that the whole thickness can be reduced.

Foretell flexible power portion includes thrust motor 7, pushes away arm gear 8 and push rod 9, pushes away arm gear and all installs in body support with thrust motor, and thrust motor drives and pushes away arm gear and rotates, pushes away the swing arm end of arm gear and push pedal one end axle and links to each other, and the push pedal other end and footboard one side axle are even.
